2002 Ford Explorer: drops..Weve replaced o2 sensors..exhaust manifold

Customer Question

My wife's 2002 Ford Explorer keeps dying on her when she comes to a stop at traffic lights. She says it shutters and idle drops low before dying. We've replaced o2 sensors on exhaust manifold but it still having problems. I am wondering if it might be a mass air flow problem? Is there a test to verify if this is problem? What is approximate cost to replace?
